Gemini Polygrab Contact Spray Adhesive for Polystyrene

Gemini Polygrab Contact Spray Adhesive for Polystyrene – Designed to bond polystyrene to itself, as well as other substrates, with no detrimental effects – A high-performance, fast-tacking, industrial contact adhesive for bonding expanded and extruded polystyrene products  a wide variety of substrates including veneers, wood, plastics, fiberglass, Glass reinforced fibre and plastics, rubber, polythene, acrylic, metal, foam and a whole host of other materials. The initial grab is so good that the substrates that have been bonded can be handled and machined almost immediately. This allows the work-piece to be completed without any down time which is crucial in a busy working environment. The nature of the spray system means that it is maintenance free, and cost effective, as compared to normal hand-applied contact adhesive. No more trowelling on of adhesive and waiting for it to go off. The sub-zero temperature stability means this is perfect for all your refrigeration and HVAC requirements. In addition, the high temperature stability gives the flexibility for underfloor heating demands.

Application

All substrates to be bonded should be conditioned at room temperature prior to fabrication. Surfaces should be dry, clean and dust free. Holding the gun parallel to the work surface and apply an even coat of adhesive aiming for 80% – 100% coverage to achieve the perfect bond. Do not allow the adhesive to puddle or concentrate in one area. Double coating the adhesive is recommended on edges of worktops or porous surfaces. Please ensure that the first coat is dry before applying the second coat. Where possible spray one surface horizontally and the other vertically to create a cross hatch when brining the two sides together. Remember that all Grabfast products are contact adhesives and forms a bond by adhering to itself, so there must be adequate adhesive applied to each substrate to be bonded. IMPORTANT – It is the users responsibility to ensure that the chosen Grabfast product is suitable for the application before use. The adhesive is dry when there is no transferrance to the finger. Bring the two sides together and using a J-roller, apply uniform pressure. Never bring the surfaces together, or apply a second coat prematurely as solvent will be trapped causing bubbles overtime.

Troubleshooting:

NEVER TURN THE CANISTER OFF UNTIL READY TO CONNECT TO A NEW CANISTER. TURNING IT OFF PREMATURELY COULD RESULT IN THE HOSE AND GUN BECOMING BLOCKED.

If the gun will not spray:

• Check the valve is turned on at the canister
• Make sure the gun wheel is wound open
• Using a spanner, remove the large front nut which secures the brass spray tip in place
• With the spray tip removed, attempt to spray the gun
• If the glue sprays, your brass tip is blocked. Please clean with Citrus cleaner and replace, or fit a new spray tip
• If there is still no flow, you have a blockage in your hose, usually caused by turning off the canister prematurely or not using the product for an extended period of time. Please contact us for guidance on how to safely remove your hose from the canister.

Spluttering or inconsistent spray pattern?

• Turn off the valve on the canister and by pulling the trigger on the gun, drain off any product in the hose.
• If your canister is cold, and been subjected to temperatures of below 15c please acclimatise the canister before turning back on. Please click here for more information on cold weather and storage.(link to cold weather page)
• Once your canister is at the optimum temperature, turn the canister on and pull the trigger on the gun to release a fresh flow of adhesive.
• Your spray pattern should now be working perfectly. If the problem still remains, please contact us for further advise.
• PLEASE NOTE – Using your canister with an inconsistent spray pattern can cause imbalances in the canister and may have negative effects on our your final bond.
